MACHINE FOR CEMENTING SOLES TO BOOTS OR SHOES.

SPECIFICATION forming part of Letters Patent No. 425,544, dated April15, 1890.

Application filed July 26, 1888` Renewed April 26, 1889. Serial No.308,767. (No model.)

To alZZ whom it may concern.-

Be it known that I, VINCENT F. LAKE, a citizen of the United States, anda resident of Pleasantville, Atlantic county, New Jersey, have inventedcertain Improvements in Machines for Cementing Insoles of Boots andShoes Prior to Lasting, of which the following is a speciiication.

My invention consists of mechanism forv applying glue or other cement tothe insoles of boots and shoes prior to lasting, the object of myinvention being to automatically and thoroughlyapply the glue or cementto the under portion of the insole throughout such portions of the sameas have to be cemented.

In the accompanying drawings, Figure l is a longitudinal section of myimproved cementing-machine on the line l 2, Fig. 2. Figi?I is atransverse section on the line 3 4, Fig. l. Fig. 3 is a sectional planview on the line 5 6, Fig. l; and Fig. 4 is a perspective view of thecementing-pad.

In the manufacture of boots and shoes by the process described in aseparate application filed by me, and bearing even date herewith, theuse of tacks is avoided and cement is used for the purpose of securingthe upper and insole together, glue being ordinarily employed, althoughany other available cement may be used.

Referring to the drawings, A is the baseplate of the machine, and B is adriving-shaft, on which is a cam B', which, through themedium of thedevices described hereinafter, imparts a reciprocating movementto thecementing-pad E, which is contained in a reservoir D, mounted on asuitable frame-work. In the reservoir D are two standards d d, whichsupport the last X, the latter having the insole a: secured to itsbottom by means of a couple of tacks or other temporary fastenings. Thecementing-pad F. is supported on two vertical rods F F', one near thetoe portion and one near the heel portion of the pad, these rods passingthrough stuffing-boxes d' on the under side of the reservoirD` and beingguided by cross-frames A' on the upright standards A2. On said standardsare studs or pins g g', to which are hung two bell-crank levers G G',the arms g"2 of these levers having at their outer ends anti-frictionrollers g3, which act upon the lower ends of the vertical rods F F. Theother arms g4 of the levers bear, respectively, against nuts h h' on arod H, which is pivoted at one end to a slide H', having a roller 71.2,which is acted upon bythe cam B, the otherv end ot' the rod beingsupported by an arm or link t' hung from the stud g. The slide II isguided in a suitable bearing I on the standards A2, and springs i' t?are connected to the base-plate of the machine and to the lower portionsof the vertical rods F F', the tendency of the springs being to draw therods against the rollers g3 of thelevers G G', and hence maintain theroller h2 of the slide II constantly in contact with the cam B'.

In order that the cementing-pad E may apply the cement accurately orWithin the proper limits to insoles of different sizes, I make said padadjustable and the toe and heel portions removable.

The pad-holder E' is divided longitudinally, each section being pivotedat c' to a head c2 on the upper portion ofthe vertical rod F,and on thefront rod F is a double-ended screw J, having a right and left handthread j', one thread being adapted to a nut j* on one section of theholder, while the other thread is adapted to a nutj3 on the othersection, so that by turning the screw .I in one direction the sectionsof the pad-holder will be separated, and by moving the screw in theoppoposite direction they will be drawn together.

On the holder E' are felt side padsk k and toe and heel pads 7a' 7a2,assorted sizes of toe and heel pads being used to accord with theadjustment of the pad-holder.

Above the reservoir D, and projecting from the standards A2, arebrackets A3, carrying set-screws m m, which bear upon the last, as shownin Fig. l, and serve to properly con- .iine the same to its seat on thestuds d d.

The adjustable nuts 7L 71.' on the shaft H permit the independentvertical adjustment of either the toe portion or heel portion of thecementing-pad so that the same may be adapted for either high or lowheeled shoes.'

In using the machine the reservoir D is partially illed with the glue orother cement, which is maintained in a liquid condition by heat orotherwise, the reciprocating motion ICO 'firmly against the under sideof the insole on the bottom of the last, the latter, with its insole,being properly supported upon the stud d and held in position thereon bymeans of the set-screws m m, which are preferably so adjusted that thelast can be readily applied to or removed from its position on the studd. On every downward movement of the pad, therefore, the upper surfaceof the saine will be coated with cement, and` on the upward movementthis cement will be applied to the' under face of the insole around theedge of the same, in proper posit-ion for securing the upper when thelatter has been lasted over the insole. I

The shaft B is preferably rotated continuously, so that the constantmovement of the cementing-pad and its holder in the reservoir D insuressuch an agitation of the cementingliquid as to prevent the same fromsettling or the formation of a scum upon it.

I claim as my invention- 1. In a machine for oementin'g the insoles ofshoes prior to lasting, the combination of a cement-reservoir, a supportfor the last, with a cementing-pad mounted in said reservoir, andmechanism for reciprocating said pad toward and from the last,substantially as described.

2. The combination of the pad-holder having opposite pivoted sections,with a right and left hand screw adapted to nuts on said sections,substantially as described.

3. The cementing-pad composed of sections adjustable to accord with thedifferent sizes of the soles, substantially as described.

4. The combination of the pad-holder with the opposite side pads, anddetachable heel and toe pads, substantially as described.

5. The combination of a cement-reservoir', a cementing-pad, mechanismfory reciprocating said pad with last-supporting posts, and overhangingbrackets having set-screws adjusted to the last, substantially as andfor the pur-l pose described.

6. The combination of the reservoir, the support for the last, with acementing-padindependently adjustable at toe and heel to accord with thecontour of the last, and mechanism for reciprocatingsaid pad toward andfrom the last, substantially as described.

7. rlhe combination of the reservoir, tie eementing-pad, vertical rodscarrying the same, a reciprocated operating-rod, and 'interposedbell-crank levers, all substantially as specified.

8. The combination of the cementing-pad, the vertical rods carrying thesame, draftsprings acting thereon, a reciprocated operating-rod, andbell-crank levers interposed be tween the reciprocated rod and th'e rodscarrying the pad, substantially as described.

9. The combination of the reservoir with the cementing-pad, the verticalrods carrying the same, the bell-crank levels-and the reciprocatedoperating-rod having nuts, whereby either of the levers may be adjustedindependently of 'the other, substantially as described.

In testimony whereof I have signed my name to this specification inthepresence of two subscribing witnesses.
